FOLDING LUNCH-BOX.

SPECIFICATION forming part of Letters Patent no. 643,862, dated.February 20, 1906.

Application filed August 18, 1899. serial No- 727,658-' (NO mod To allwhom it may concern:

Beit known that I, ABRAM SNYDER BROWN, a citizen of the United States,and a resident of Tyrone, county of Blair, State of Pennsylvania, haveinvented a new and useful Improvement in Folding Lunch-Boxes, of whichthe followingis a full, clear, and exact description, reference beingbad to the accompanying drawings, making part of this specification.

My invention relates to an improvement in folding lunch-boxes; and itconsists in the peculiar construction and arrangement of partshereinafter more fully described, and particularly pointed out in theclaim.

In the accompanying drawings, Figure 1 is a perspective view of myimproved folding lunch-box, showing the same arranged for use. Fig. 2 isa similar view showing the same folded as when not in use. Fig. 3 is aplan view showing the lunch-box flattened out and extended. Fig. 4 is asectional view taken on the line 00 ocof Fig. 2 on an enlarged scale,showing the pasteboard parts, the linings, and covers thereof and thepockets formed between said pasteboard parts and the linings.

The four sides A, B, C, and D of my lunchbox, Which are each ofrectangular form and are of similar shape, are arranged side by side inseries and flexibly joined together on the lines 1 2 3, as shown, andadapted to be folded on said lines.

To the ends of the bottom side B are attached the square end pieces E byflexible joints along the lines 4. Each of these end pieces E isprovided on its inner side with a pocket F, which are formed between thesaid end pieces and the linings thereof, and to the sides of the endpieces are flexibly jointed flaps G, which are triangular in form andadapted to be folded inwardly over the end pieces on the lines 5.

To the outer side of the top side piece D is attached an overlappingflap H, which is connected thereto by a flexible joint along the line 6,and triangular flaps K are flexibly attached to the ends of the toppiece along the lines 7. The said flaps H K are thus adapted to befolded over the inner side of the top piece D, as indicated indotted'lines in Fig. 3.

The side pieces A O are provided at their ends with pockets L M,respectively, which are formed between said side pieces and theirlinings, adapted to receive the flaps G of the end pieces when the partsare arranged in position to form a box, as shown in Fig. 1, the sidepieces A 0 being first upturned, the end pieces E being then upturnedand having their flaps G inserted in the pockets L M of the side pieces,and as the top piece D is turned down in closing the box its end flaps Kare inserted in the pockets F of the end pieces, whereby the said endpieces are effectually prevented from opening while the box is in use.The flap H on the free side of the top piece D folds over and overlapsthe outer side of the side piece A, thus effectually closing the jointbetween the said top and side pieces. A strap 0 is passed around the boxto secure it when filled and to enable it to be easily carried, a loop Pbeing provided on the said strap for the insertion of a finger or forthe attachment of a belt or strap around the shoulders of a wearer.

When folding or knocking down the box, the flaps G are folded againstthe inner sides of the end pieces E, the latter are turned outwardlyunder the bottom piece B, the side piece A is folded on said bottompiece, the side piece 0 is folded against end pieces E and flaps G, theflaps H K are folded inward against the top piece D, and the latter isthen folded against the side piece 0, with the flaps H K between them.Hence when the box is thus folded only the outer sides of the side pieceA and top piece D are exposed.

I prefer to manufacture my improved folding lunch-box of pasteboard,provided. with suitable linings a and covered on the outer sides withcloth, as at b; but the box may be made of leather, wood, metal, orother suitable material, if preferred, as will be readily understood.

When the box is folded, the strap 0 is passed around it from end to end,as indicated in Fig. 2.

My improved folding lunch-box is exceedingly neat and attractive inappearance, may be very cheaply manufactured and sold for a low price,and is very compact and serviceable.

' Having thus described my invention, I claim The folding lun ch-boxcomprising the front N 7 side piece A, the bottom piece B, the rear sideside projecting flaps G adapted to enter the piece C and the top pieceD, arranged in sepockets L M of the side pieces, all constructed riesand flexibly jointed together, said side and arranged substantially asdescribed. pieces A, 0, having the end pockets L, M, re- In testimonywhereof I have set my hand,
